HOW to SUPPRESS A FEATURE GROUP

HI Guys,

I´m having some trouble to identify how can I supress a feature group and those members.
I´m trying to replace the find object from journal and I´m not sure with class I can use for it.

Dim featureGroup1 As Features.FeatureGroup = CType(workPart.Features.FindObject("FEATURE_SET(60)"), Features.FeatureGroup)

Thanks in Advanced.
TH
